Finding a final amount in a word problem on exponential growth or decay
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 185 grams of a radioactive isotope, how much will be left after 3 half-lives?
Use the calculator provided and round your answer to the nearest gram.
Answer:
25 grams
Step-by-step explanation:
Three half live
1/2 * 1/2 * 1/2 = (1/2)³ = 1/8
There would be 1/8 of the original amount left
185 * 1/8 = 23.125
Rounded
25 grams
Please help! Thanks in advance!!! :3
Linda walked a total of 26 1/4 miles during a 4 day period. The distances she walked are described below.
• She walked 6 1/3 miles the first day.
• On the second day, she walked 9 1/2 miles
• She walked 5 1/4 miles on the third day.
How far did she walk on the fourth day?
[tex]1st \: day + 2nd \: day + 3rd \: day + 4th \: day = 26\frac{1}{4} \\ 6\frac{1}{3} + 9\frac{1}{2} + 5\frac{1}{4} + x = 26\frac{1}{4} \\ \frac{253}{12} + x = \frac{105}{4} \\ x = \frac{105}{4} - \frac{253}{12} \\ x = \frac{31}{6} = 5\frac{1}{6} [/tex]
Find the distance between the pair of points.
(2, -2), (-5, -2
Answer:
7
Step-by-step explanation:
Answer:
7 units
Step-by-step explanation:
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Plug in what you know.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(49) + (0) }[/tex]
Add.
[tex]d = \sqrt{(49)[/tex]
Evaluate the radical.
d = ±7
Since distance cannot be negative, our answer is 7.
The distance between the two points is 7 units.
Hope this helps!

Jemima filled one fourth of a barrel with compost on Saturday. Then she filled the remaining space with 4,200g of compost on Sunday. How many kilograms of compost are in the barrel
Answer: 5.6kg
Step-by-step explanation:
Since Jemima filled one fourth of a barrel with compost on Saturday, then the remaining space will be:
= 1 - ¼ = ¾
Since the remaining ¾ space is filled with 4200g of compost, then the compost in the barrel will be
¾ × x = 4200g
0.75 × x = 4200g
0.75x = 4200g
x = 4200g/0.75
x = 5600g
Since 1000g = 1kg
5600g = 5600/1000 = 5.6kg
There is 5.6kg of compost in the barrel.
If you were to use the “Completing the Square” method to solve the equation below for k, what number would you add to both sides of the equation? k 2- 8k = -4
A) 16
B) –16
C) 24
D) –24
Answer:
The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.
Step-by-step explanation:
To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

Answer:
9x2 +42x + 24 is (x + 4) (9x + 6)
9x2 + 30x + 24 is (3x + 6) (3x + 4)
9x2 + 58x + 24 is (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)

after locating the tenth, we follow rounding principles. if the number to the right is 0-4, the place value you are looking at stays the same (which happens in our case). If the number to the right is 5+, we round the number to the left up so if it was 12.27, it would be 12.3

A water container has 19.5 litres of water in it. A cup holds 210 ml of water. At most 92 cups can be filled completely from the water container. Explain why
Step-by-step explanation:
Given
A container has 19.5 liters of water
A cup can hold 210 ml of water
1 L is equivalent to 1000 ml
So, 19.5 L is equivalent to [tex]19.5\times 1000=19,500\ ml[/tex]
So, the number of requires to hold this much water
[tex]\Rightarrow n=\dfrac{19,500}{210}\\\\\Rightarrow n=92.85\ \text{cups}[/tex]
92.85 implies 92 full cups and 1 cup which is partially filled. Hence, almost 92 cups can be filled completely.

Answer:
m =(-7-√73)/2=-7.772
Step-by-step explanation:
Answer:
m=−7/2+1/2√73 or m=−7/2+−1/2√73
Step-by-step explanation:
Let's solve your equation step-by-step.
m2=−7m+6
Step 1: Subtract -7m+6 from both sides.
m2−(−7m+6)=−7m+6−(−7m+6)
m2+7m−6=0
For this equation: a=1, b=7, c=-6
1m2+7m+−6=0
Step 2: Use quadratic formula with a=1, b=7, c=-6.
m=−b±√b2−4ac/2a
m=−(7)±√(7)2−4(1)(−6)/2(1)
m=−7±√73/2
m=−7/2+1/2√73 or m=−7/2+−1/2√73
